Suggested Bleeding Procedure - External Slave Cylinder

If the truck is a 1987 or prior model, 1988 model with a 7.3L Diesel, 7.5L EFI gas engine or the smaller family of engines with a Warner T-18 four speed transmission, proceed as follows:
1. Remove the master cylinder reservoir cap and diaphragm.
2. Check the fluid level to be sure it is at the step diameter of the reservoir. Do not over fill.
3. From below the truck, push the release lever slowly towards the front of the truck several times. Figures 11 & 12.
4. If it will not move, the master cylinder pushrod is not set correctly. See repair Step # 19.
5. Check the fluid level, then replace the diaphragm and cap.

Suggested Bleeding Proc - Internal Concentric Slave CYL.

If the truck has a concentric slave cylinder, proceed as follows:
1. Operate the clutch pedal at full stroke, 10-20 times.
2. Check the fluid level at the change in diameter part of the reservoir. Do not over fill.
3. Have an assistant depress the clutch pedal slowly and hold it down.
4. Open the slave cylinder bleed screw until air has escaped.
5. Close the bleed screw and have the assistant release pedal.
6. Repeat this cycle from step 3 several times until there is no sign of air. Be sure to keep the reservoir topped to the correct level.
7. Replace the diaphragm and reservoir cover.
8. Operate the clutch pedal at full stroke 10-20 times.
